Hi Hempfieldhunter ...

Bear hunting for success is very time consuming. I'm not sure about your area in PA ... when's bear season ? Yep - they're sleeping in the winter - so the best time to scout is Spring. When they wake up - they're looking for food. In spring they eat grass and vegetation and possibly some carcasses that have perished during the winter that they find. Their diet is very flexable - they love "sweet" - so if you can find some berry patches - that's a good spot to watch.
I don't know if you can legally bait bears in PA - so even putting dead fish out could get you in a mess of trouble ... know your laws first.

If you can bait - then it's a bonus.

To "lure" a bear to a specific area that you may want to hunt - fresh fish could work ... but rotten fish works great. Simply fill a covered pail with fish guts and set it in the sun for a couple weeks - dump that at your site you want to hunt ... and follow it up with fresh meat scraps from your butcher. Continue with the meat scraps at least twice a week until 2 or 3 weeks before hunting season - then do it EVERY day. That gets the bears on a schedule.

If you're hunting with a bow - I'd suggest a climber tree stand - and when you're baiting - take off your gloves and run your hands all over the trees in the area - so that you leave your scent there and the feeding bears won't be alarmed by your scent.

Next step - set up - and kill !
Good Luck
